Sumitomo Metal Mining (Japan)

The fields where it stands highest, over all time, ranked among every institution above the floor in each field.

Each strip is that field’s whole ranked pool, with the notch where Sumitomo Metal Mining (Japan) sits in it, in the colour of the band that rank falls in. The track under the rate is the rate itself: it carries no world mark, because the world rate differs by field (from about 6% to 21% in this record).

Location quotient across every field it publishes in: outside the ring is more than an institution of this size would be expected to publish, inside it is less.
